In Switzerland July 10, 1946 Section 1, Public Law 690, August s, 1946 Patent expires July 10, 1966 L Claims. (Cl. 19159) The cans used in spinning mills, for instance with drawing frames and serving for receiving slivers are ordinarily placed on plate supports located below the filling device proper on the floor or in a recess of the latter. In order to fill the slivers properly into the cans separate gear means are provided to impart to the plate supports and thereby to the cans either a rotary movement about their axis or a movement of the plate supports or of the cans respectively along a closed curved path. The-mounting of said gear means on the floor is not favourable as in sweeping or cleaning of the floor fibers and dirt are apt to adhere to the gear means causing frequent interruptions in the working. In case the construction of the mill building does not permit recesses in the floor the whole machine must be placed at a correspondingly higher level which instance renders the attendance on the machine more difficult. The fact that the plate supports are not mounted on the machine frame proper disturbs the appearance of the machine. As the cans are loosely placed on the plate supports they are apt to be overturned.

In order to overcome these disadvantages the device according to the present invention for placing slivers into cans comprises holders arranged on the machine below the coiler, heads, in which holders the cans are exchangeably suspended.

This arrangement of the cans permits in a simple manner a safe mounting of the cans on the machine and a saving in space in the vertical direction of the machine.

The holders of the cans may at the same time with advantage be used for imparting a suitable movement to the cans for the proper placing of the slivers therein; a supporting frame for a plurality of holders for the cans may preferably be provided. The whole drive for imparting said movement may be arranged in the machine proper in a. dust-proof manner so that it is able to work without interruptions for a long time.

A constructional example of the device according to the invention is illustrated on the accompanying drawings, in which Fig. 1 shows the device in elevation with parts in a vertical section,

Fig. 2 is a top view of Fig. 1 with some parts omitted, and

Fig. 3 shows in a perspective view a driving element.

Below the coiler head I of known construction having an eccentric discharge channel for the sliver indicated by a dash and dot line the can 2 is suspended. It is assumed that a plurality of coiler heads l are arranged in a row and a can 2 is provided below every coiler head. The-cans 2 are suspended in holders consisting of spring arms 3 fixed to a supporting frame 4. Every two spring arms 3 form together with an extension 5 of the supporting frame 4 a resilient clamp acting as holder or seat for a can 2. Each holder has the approximate shape of a circular arc, the circumference of which is somewhat larger than a semi-circle and the radius of which corresponds approximately to the outer radius of a can. The supporting frame 4 rests in two points on an enclosed thrust bearing 6 carried by a stud 1. Two arms 4 of the frame 4 bear against a fixed rib 8 of the machine frame 9. Each stud 1 is fixed to a crank l0 rotatably mounted on the machine frame 9 and driven by a worm-drive ll.

When the machine works the supporting frame 4 for the cans is moved in a horizontal plane by the worm drive I l, the arms 4' of the frame gliding on the lower face of the fixed rib 8. The supporting frame 4 performs a circular movement determined by the rotation of the cranks. By the superposition of the movement of the supporting frame 4 and of the rotation of the coiler head I associated with each can 2 the sliver passing through the coiler head is placed in cycloidal windings withoutadditional twisting into the can 2. In some cases it is of special advantage not to impart a twist to the sliver during this stage of work.

The arms of the cranks II] are provided with three holes I2 arranged in different radial distances into any of which the crank pin 1 may be inserted. Thereby the movement of the cans relative to the coiler heads I may be adjusted in accordance with the shape and sizeof the cans.

I claim:

1. In a machine for preparing slivers for spinning, a main frame, a plurality of coiler heads having openings for delivering slivers, cans for receiving slivers delivered from each respective coiler head, clamping means for exchangeably suspending said cans below said coil heads, a can supporting frame carried by the main frame to which all of said clamping means are attached, and means to impart to said can supporting frame a circular movement in a horizontal plane.

2. In a machine for preparing slivers for spinning, a main frame, a plurality of coiler heads delivering slivers, cans for receiving slivers from the respective coiler heads, clamping means for exchangeably suspending said cans below said.

coiler heads, a supportin frame to which all of said clamping means are attached, suspension members by which said supporting frame is connected to said main frame, and means cooperating with said suspension members for imparting a circular movement in a horizontal plane to said supporting frame and thus to the clamping means attached thereto and the cans carried thereby.

3. In a machine for preparing slivers for spinning as claimed in claim 2, a rib on saidmain frame, and two arms on said supporting 'frame cooperating with said rib for guiding said supporting frame. r 1 7 4. In a machine for preparing slivers. fpr spin ning, a main frame, a plurality of coiler heads delivering slivers, a can for each coilerhead for receiving said slivers, a supporting frame carried by the main frame, holding means carried 'by said supporting frame for exchangeably -suspending said cans below said coiler heads, and means to impart to said supporting frame and the holding means and cans a circular movement in a horizontal plane.

5. In a machine for preparing slivers for spinning, a main frame, a plurality of coiler heads delivering slivers, a can for each coiler head for receiving the slivers therefrom, a supporting frame carried by the main frame holders carried by said supporting frame for suspending said cans below said coiler heads, cranks for imparting to said supporting frame and the holders carried thereby a circular movement in a horizontal plane, the'crank arms of said cranks being variable to vary the movement of said holders.
